Properties of Stars
This aspect of a star tells us what temperature it is.
What is its color?
When a star runs out of hydrogen and begins to die it turns into this.
What is a red giant or red supergiant?
This type of galaxy is oval shaped.
What is an elliptical galaxy?
All stars and solar systems form from this.
What is a nebula?
This planet has a giant storm in it's atmosphere that has been raging for hundreds of years.
What is Jupiter?
This layer of the sun is where all solar activity such as flares and prominences take place.
What is the chromosphere?
This EM wave can cause sunburns on your skin.
What are UV rays?
List the four different star sizes in order from smallest to biggest.
What is dwarf, main sequence, giant, and supergiant?
These kinds of stars have the shortest life spans.
What are larger stars?
This type of galaxy forms from multiple galaxies colliding.
What is an irregular galaxy?
This component of the universe is larger than a star but smaller than a nebula.
What is a solar system?
This is the hottest planet in our solar system.
What is Venus?
The sun is made up of this many layers.
What is 6?
This EM wave is felt as heat.
What are infrared waves?
This aspect of a star depends on its distance from Earth.
What is apparent brightness or magnitude?
An average-sized star is considered this once it is completely dead and no longer giving off any energy at all.
What is a black dwarf?
This type of galaxy contains older stars in the center and newer stars on its arms.
What is a spiral galaxy?
This unit of measurement is used to measure extremely long distances in space.
What is a lightyear?
This planet is the only one in our solar system with no atmosphere.
What is Mercury?
This process combines hydrogen to create helium while also producing heat and light.
What is nuclear fusion?
This EM wave falls in the middle of the spectrum.
What is visible light?
What is a star’s absolute brightness called?
Luminosity.
When a large mass star dies, it eventually becomes a black hole or neutron star, but not before exploding into this.
What is a supernova?
This specific galaxy measures 100,000 light years across.
What is the milky way galaxy?
These two elements make up a star.
What is hydrogen and helium?
This gas gives Uranus & Neptune their blue colors.
What is methane?
Sunspots exist on this layer of the sun.
What is the photosphere?
This EM wave has the longest wavelengths.
What are radio waves?
A star's absolute brightness is measured from this standardized distance.
What is 10 parsecs or 32.6 light years?
When an average-sized dying star begins to shed its layers it is considered this.
What is a planetary nebula?
Galaxies are slowly moving away from each other due to this.
What is the expansion of the universe?
Our sun is this color.
What is yellow?
This substance on Mars' surface gives it it's red/orange color.
What is iron oxide or rust?
This element is most abundant inside our sun.
What is hydrogen?
This EM wave has the highest frequency.
What are gamma rays?
